Frequently Asked Questions
Is it safe to add a watermark to my confidential PDF?
Yes. This tool is **100% secure**. All processing happens locally in your web browser. Your PDF file is never uploaded to any server, so your sensitive information remains completely private.
Can I add my logo as a watermark?
Absolutely. Select the "Image" tab in the options panel and upload your logo (PNG or JPG files are recommended). You can then adjust its position, opacity, and rotation just like a text watermark.
How do I make the watermark "tiled" across the page?
In the "Positioning" section, simply check the box labeled "Tile watermark". This will automatically repeat your text or image watermark across the entire page, providing maximum coverage.
Can I add a watermark to only the first page?
Yes. In the "Page Range" field, simply type "1". You can specify any page or range, such as "1, 3-5, 10-end" to apply the watermark only to those specific pages.
